GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 583,526, dated February5, 1895.

Application filed May 31, 1893. Serial Ne.47 6,032. (No model.)

To 09% whom it may concern.-

Be it known that I, JEROME F. BUSEY, of Venice,in the county ofWashington and State of Pennsylvania, have invented a new and usefulImprovement in Gas-Burners, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification, in which Figure l is a verticalsectional view. Fig. 2 is a cross-section on the line II-II of Fig. 1,and Fig. 3 is a modification of the lamp chimney,

lily invention relates to the gas burners employed for illuminatingpurposes, and is designed to produce a cheaper and more efficient burnerthan has heretofore been attained.

In the drawings, 2 represents the cylindrical air tube of the burnerwhich is open at the top and bottom. This tube is surrounded by theshell 5. At the base of this tube and secured to the shell by a threadon the outer surface of the shell is a flared flange 3 provided with athread on its lower outer surface, which second thread engages with athread on the inner surface of the perforated airregulating cap 4, whichcap is provided with a solid bottom piece, and is adapted to screwupward on the flange-piece 3, so as to reduce the number of perforationsbelow the flangepiece and consequently reduce the amount of air whichpasses through the perforations into the air-tube 2.

The annular shell 5, which surrounds the air-tube 2, may be formed of asuitable casting, and it is secured to the air-tube 2 and is centeredabout the same by the screws 6. The bottom of this shell is closed byfitting the casting tightly around the air-tube 2; but, at the top,thereisaverynarrowspace between the air-tube,which tubeextends slightly abovethe casting, and the casting, through which space the gas passes fromthe chamber.

On the outerface of the casting 5 is a screwthread into which fits theinterior thread formed on an upturned collar of the baseplate 7 of themixing-chamber 8. This mixing-chamber is formed of the solid base-plate7 and a collar 9, the lower portion of which is perforated, and theupper outer portion of which is threaded so as to engage with a threadformed on the inner face of the upturned portion of the annular gallery10, which is provided with airperforations l1.

Fitting in the upper portion of the mixingchamber 8 is an air-deflectingring 12, the lower portion of which extends in the chamber 8 inwardly atan angle toward the center so as to deflectthe air passing in throughthe perforations in the side of the miXing-cham her toward the center,and the upper portion of this ring above the mixing-chamber flaresoutwardly in a reverse direction so as to spread the gas which passesthrough the space between the air-tube 2 and the casting 5.

Fitting on the gallery 10 is-the deflector 13, the annular wall of whichis in the shape of the frustum of a cone. Secured to the upper portionof this deflector by screw threads is the gallery 14, which supports theglass-chimney 15. This chimney is of peculiar shape, having aregularconcave curve from its base to its top asjshown in Fig. 3, or it may beconvex in shape near its base ending in a shoulder 17, and a concaveupper portion 18 near its top as is shown in Fig. 1. The extreme upperend portion of the chimney may be cylindrical in form.

Gas is admitted to the gas-chamber between the tube 2 and shell 5 by thesupply-pipe 19, which is provided with two or more stopcocks 20, bymeans of which the supply of gas may be regulated so as to preventroaring of the flame.

The advantages of my invention will be apparent to those skilled in theart; and within the scope of my invention, as defined in the claims,modifications in the form and construction of the parts may be made bythe skilled mechanic.

Having thus described my invention, what I' claim, and desire to secureby Letters Patout, is-

1. In a gas-burner, the combination of an air-tube, a surroundinggas-chamberhaving an annular opening and below the level of the chimney,a perforated gallery around the mouth of the air tube and gas opening,and
